It has been adopted by CEPT multilateral meeting on 04 July 2007 and has come into force on 01 September 2007. The Arrangement contains technical characteristics for T-DAB and multimedia systems to operate in the L-band. Since the adoption of MA02revCO07, a number of systems have been identified as potential user of the L-band for which the characteristics may slightly differ from those given in the Arrangement. Therefore, this ECC Report provides additional technical characteristics relating to: Hand-held reception of TV, audio, datacast and multimedia services Programme Making and Special Events (PMSE). It also indicates that new systems are under development such as Next Generation Handheld (NGH) which may need to be further considered at a later stage. In addition, it provides additional guidance on the maximum allowable PFD levels of the satellite networks to protect T-DAB systems for coordination with S-DAB systems in the sub-band 1467 MHz to 1479.5 MHz. Finally, the report provides guidance to administrations in the application of the envelop concept in the framework of the MA02revCO07 Arrangement.

INTRODUCTION 1. By this Order, we authorize AfriSpace, Inc. (AfriSpace)1 to launch and operate the AfriStar-2 satellite in the geostationary-satellite orbit (GSO) at the 21° East Longitude (E.L.) orbital location. AfriStar-2 is controlled from the United States and is capable of providing Broadcasting-Satellite Service (sound) (BSS (sound)) to Africa and Europe on a non-common carrier basis. We authorize AfriStar-2 to operate downlinks within 2.6 megahertz of spectrum in each polarization with a center frequency of 1479.5 MHz. We also authorize AfriSpace to utilize feeder links and telecommand links for the AfriStar-2 satellite in the 7025-7075 MHz frequency band, to operate its telemetry link for the AfriStar-2 satellite at a center frequency of 1491.7 MHz, and to co-locate the AfriStar-2 satellite at 21° E.L. with the AfriStar-1 satellite currently in orbit. In addition, we grant AfriSpace a waiver of the Commission’s rule regarding transponder saturation flux densities for the AfriStar-2 satellite.2 These authorizations give AfriSpace the capability to continue to provide service to existing customers despite unanticipated technical difficulties experienced by the AfriStar-1 satellite and to serve new customers, conditioned on AfriSpace complying with the applicable laws, regulations, rules, and licensing procedures of any countries it proposes to serve.

    November 23, 2016 VIA ELECTRONIC FILING Marlene H. Dortch, Secretary Federal Communications Commission 445 12th Street, S.W. Room TW-A325 Washington, DC 20554 Re: SAT-ASG-20161025-00101 Application for Assignment of Authorizations for AfriStar-1 and AfriStar-2 (call signs S2367 and S2666) from Yazmi USA, LLC (“Yazmi”) to Silkwave Africa, LLC (“Silkwave”). Dear Ms. Dortch: At the request of FCC staff, we are submitting this letter in the docket for the above-named application (the “Application”) to supplement statements made in the Public Interest Statement of that Application. The Public Interest Statement explained that the AfriStar-1 satellite will be initially controlled by Intelsat pursuant to an agreement between Intelsat, Silkwave, and an affiliate of Silkwave. The affiliate of Silkwave referred to is New York Broadband LLC, a U.S. limited liability company (“NYBB”). NYBB is affiliated with Silkwave because Chi Capital, which owns 100% of Silkwave, also has a minority ownership interest in NYBB. NYBB owns an Australian-licensed satellite, AsiaStar, which is operated by Intelsat pursuant to an agreement between NYBB and Intelsat (the “NYBB Agreement”). The AsiaStar satellite was also acquired from Yazmi pursuant to a series of earlier transactions not requiring FCC approval. The AfriStar-1 satellite is currently being operated by Intelsat pursuant to a separate agreement between Yazmi and Intelsat (the “Yazmi Agreement”). The parties intend that, following the transfer of the AfriStar-1 license to Silkwave, Intelsat will continue to operate the AfriStar-1 satellite on Silkwave’s behalf, either through an amended Yazmi Agreement, or more likely through an amended NYBB Agreement that includes the AfriStar-1 satellite and adds Silkwave as a party.

The service works by receiving a specialised digital TV broadcast signal from the air in much the same way as televisions at home will do in future. Channel guides will also be broadcast allowing users to keep abreast of the latest programs on air. It is not the same as a streaming video service over 3G or GPRS, but one which is optimised for longer period TV viewing by large numbers of simultaneous users with high picture quality and low battery power consumption.
